I can't reproduce this one nor #6198.

So either were corrected at some point by something else (but nothing obvious for that), or they depends on something else. They both seem linked to ajax timeout, so I suspect something like an error in the JS returned interpreted differently by browser, or something like network condition...

Nico, do you still get them ?

(see also #6198)

So more information: it seems to happen with firefox 31, but not firefox 35.

I can't reproduce it either with firefox 31.4esr.

Nico, could you check it's still here ?

OK, I reproduced it one time.

The problem seems to be that for some reason, the POST:

ruleCompliances = {};
              recentChanges = {};
              recentGraphs = {};
              refreshTable("grid_rules_grid_zone", [{"name": "Global configuration for all nodes", "id": "32377fd7-02fd-43d0-aab7-28460a91347b", "description": "", "applying": false, "category": "", "status": "In application", "trClass": "tooltipabletr  ", "checkboxCallback": function(checked) {liftAjax.lift_ajaxHandler('F59769931248DXIP5V=' + encodeURIComponent(checked), null, null, null);}}, {"name": "Test new rule", "id": "2f706b87-4334-45ba-8f59-72675139b2f9", "description": "", "applying": false, "category": "", "status": "In application", "trClass": "tooltipabletr  ", "checkboxCallback": function(checked) {liftAjax.lift_ajaxHandler('F59769931249UNCJY5=' + encodeURIComponent(checked), null, null, null);}}, {"name": "test reporting cass\u00e9", "id": "2fcbbe40-725c-4676-9432-aeac358f4a5f", "description": "", "applying": false, "category": "", "status": "In application", "trClass": "tooltipabletr  ", "checkboxCallback": function(checked) {liftAjax.lift_ajaxHandler('F59769931250KDS5XN=' + encodeURIComponent(checked), null, null, null);}}]
);
              liftAjax.lift_ajaxHandler("F59769931251MVSSN3=true", null, null, null);
              liftAjax.lift_ajaxHandler("F59769931252N1G5GL=true", null, null, null);

Is fired two-time, and the second time, the last liftAjax.lift_ajaxHandler leads to the "server can not be contacted at this time".

So, there is two problems:
- why the post is fired two times ? At least, it's wasting resources, at worst it's the door to double-actions
- why firing that handler leads to an error ?

For the last question, it seems that the problem is that the result of the callback ask for refreshing the rule grid, but that there is no more rule grid at that point (since it's deleted).

var ruleTable = $('#'+"grid_rules_grid_zone").dataTable();
            var currentPageRow = ruleTable._('tr', {"page":"current"});
            var currentPageIds = $.map( currentPageRow , function(val) { return val.id});
            computeChangeGraph({"x": [], "y": []},"32377fd7-02fd-43d0-aab7-28460a91347b",currentPageIds);
            computeChangeGraph({"x": [], "y": []},"2f706b87-4334-45ba-8f59-72675139b2f9",currentPageIds);
            computeChangeGraph({"x": [], "y": []},"2fcbbe40-725c-4676-9432-aeac358f4a5f",currentPageIds);

The two last comments were for #6198.

For this one, it seems that sometimes, we don't send back all the compliance.
For example, I have two rules, and the refresh returns only one compliance:

Post 1: return of the refresh:

ruleCompliances = {};
              recentChanges = {};
              recentGraphs = {};
              refreshTable("grid_rules_grid_zone", [{"name": "Global configuration for all nodes", "id": "32377fd7-02fd-43d0-aab7-28460a91347b", "description": "", "applying": false, "category": "", "status": "In application", "trClass": "tooltipabletr  ", "callback": function(action) {liftAjax.lift_ajaxHandler('F1296830236323D5RZM0=' + encodeURIComponent(action), null, null, null);}}, {"name": "Nodes only", "id": "ff31e98b-7325-4926-a8d8-fe551d2c3be1", "description": "", "applying": false, "category": "", "status": "In application", "trClass": "tooltipabletr  ", "callback": function(action) {liftAjax.lift_ajaxHandler('F1296830236324L00WGP=' + encodeURIComponent(action), null, null, null);}}, {"name": "Root only", "id": "a3a796b9-8499-4e0b-86c5-975fc5a13505", "description": "", "applying": false, "category": "", "status": "Not applied", "trClass": "tooltipabletr disabledRule ", "reasons": "Rule disabled, No policy defined", "callback": function(action) {liftAjax.lift_ajaxHandler('F1296830236325AFKG4A=' + encodeURIComponent(action), null, null, null);}}, {"name": "A new rule!", "id": "2278f76f-28d3-4326-8199-99561dd8c785", "description": "", "applying": false, "category": "", "status": "Not applied", "trClass": "tooltipabletr disabledRule ", "reasons": "Rule disabled, No policy defined, Empty groups", "callback": function(action) {liftAjax.lift_ajaxHandler('F1296830236326GIEXRV=' + encodeURIComponent(action), null, null, null);}}, {"name": "Test new rule", "id": "f300ef37-55a8-4e7f-947c-bc192599bd6d", "description": "", "applying": false, "category": "", "status": "Not applied", "trClass": "tooltipabletr disabledRule ", "reasons": "Rule disabled, No policy defined, Empty groups", "callback": function(action) {liftAjax.lift_ajaxHandler('F1296830236327IBRLLF=' + encodeURIComponent(action), null, null, null);}}]
);
              liftAjax.lift_ajaxHandler("F1296830236328AUEL1W=true", null, null, null);
              liftAjax.lift_ajaxHandler("F1296830236329OJ0LRE=true", null, null, null);

Post 2 (first ajax handler ?): build compliance bar: only one !!

$("#compliance-bar-32377fd7-02fd-43d0-aab7-28460a91347b").html(buildComplianceBar([0.0, 50.0, 0.0, 0.0, 0.0, 50.0, 0.0, 0.0]));
                ruleCompliances['32377fd7-02fd-43d0-aab7-28460a91347b'] = [0.0, 50.0, 0.0, 0.0, 0.0, 50.0, 0.0, 0.0];

Post three: build change graphs:

var ruleTable = $('#'+"grid_rules_grid_zone").dataTable();
            var currentPageRow = ruleTable._('tr', {"page":"current"});
            var currentPageIds = $.map( currentPageRow , function(val) { return val.id});
            computeChangeGraph({"x": [], "y": []},"2278f76f-28d3-4326-8199-99561dd8c785",currentPageIds);
            computeChangeGraph({"x": [], "y": []},"a3a796b9-8499-4e0b-86c5-975fc5a13505",currentPageIds);
            computeChangeGraph({"x": [], "y": []},"ff31e98b-7325-4926-a8d8-fe551d2c3be1",currentPageIds);
            computeChangeGraph({"x": [], "y": []},"f300ef37-55a8-4e7f-947c-bc192599bd6d",currentPageIds);
            computeChangeGraph({"x": [], "y": []},"32377fd7-02fd-43d0-aab7-28460a91347b",currentPageIds) ;

So, why only one ?
